Air-conditioner module and use thereof

Abstract

The heat and mass exchange (HMX) module comprises a plurality of plates in a spaced-apart arrangement and provided with a plurality of air channels for air flow and a plurality of liquid channels for flow of liquid, wherein a liquid channel is embodied at a surface of a plate and is arranged adjacent to an air channel with a mutual exchange surface, which liquid channel is provided with an entry and an exit. The module further comprising a distance holder arranged between a first and a second adjacent plates. The entry of the liquid channel is defined as a plurality of entry regions spaced apart by means of closed regions, which entry regions define entry points for the liquid into and onto the layer of wicking material, in which closed regions the distance holder extends between the first and the second plate.

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a 371 national stage application of PCT Patent Application No. PCT / NL2015 / 050680, entitled “Air-conditioner module and use thereof,” filed on Sep. 30, 2015, which claims priority to Dutch Patent Application No. 2013565 filed on Oct. 2, 2014, the entire contents of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The invention relates to a heat and mass (HMX) exchange module comprising a plurality of plates in a spaced-apart arrangement and provided with a plurality of air channels for air flow and a plurality of liquid channels for flow of liquid, such as liquid desiccant material, wherein a liquid channel is embodied at a surface of a plate and is arranged adjacent to an air channel with a mutual exchange surface, which liquid channel is provided with an entry and an exit and which air channel is provided with an inlet and an outlet.[0003]The invention further relates to an conditioner apparatus ...

AI Technical Summary

Benefits of technology

The technical effect of this patent is to provide an HMX module that can accurately distribute liquid onto a plate and reduce the risk of carrying over liquid desiccant into the air-stream.

Problems solved by technology

Such a salt solution however have as disadvantages that LiCl may be hazardous for human health and that the concentrated LiCl solution is highly corrosive.

This reduces the overall both heat and mass transfer efficiency relative to a counter current flow design.

The use of a chamber filled with a sponge has however the disadvantage that the air should be flowing through the pores of the sponge.

This evidently requires a high air pressure, and it still may lead to carry-over due to the irregular flow pattern that the air has to go.

This has the disadvantage of desiccant droplet creation and consequent carryover into the air stream.

However, such a distribution system still has a risk of carryover.

The distributor cannot cancel out this flow direction of the liquid desiccant, at least not completely.

However, it has been found that this type of module is prone to leakage of liquid desiccant into an air channel rather than into the wicking layer acting as liquid channel.

The resulting situation is one wherein the liquid desiccant flows in an uncontrolled manner and the assembly will loose its stability.

However, also in the preferred embodiment, leakage cannot be prevented.

Being at the surface, there is a risk of flowing into the air channel, particularly at higher flow rates of liquid desiccant.
